if your going to run another volume control system why not eliminate the line 3 all together your just adding more to the chain that's not necessary. if its to get the switching ability of the preamp then buy a quality switch box. your just adding noise to the system and burning tubes for no reason. if you want the tube sound then buy a tube buffer stage.
Sonic Frontiers Line 3 unity gain
I'm searching to set unity gain on my Sonic Frontier Line 3 preamp to run the leedh volume control from a Lumin T2. HT setting is only for single ended connections and I use balanced. Is there a particular setting to achieve this?
